While he might not be a household name today, the Dutch textile salesman ground and polished his own lenses, and was the first human to discover the existence of bacteria, single celled creatures, and spermatozoa. Working from his dwellings above a marketplace in the Dutch city of Delft, his home-made lenses were so finely constructed that some of the organisms he discovered were not seen again for another century. Doodle designer Gerben Steenks says, “I chose to make it an animated Doodle to show the ‘before and after’ experience that Antoni van Leeuwenhoek had — looking through a microscope and seeing a surprising new world.” Van Leeuwenhoek wrote in a letter to the Royal Society of London that he had seen “little animals” in lake water he had collected for his first microscopic experiment. “He saw a whole world in a drop of water,” writes Google. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4542058/antoni-van-leeuwenhoek-google-doodle/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4542058/antoni-van-leeuwenhoek-google-doodle/"},"headline":"New Google Doodle Celebrates Antoni van Leeuwenhoek, Inventor of Microbiology","datePublished":"2016-10-24T03:58:52.000Z","dateModified":"2026-04-13T07:37:54.289Z","description":"The doodle represents the \"little animals\" Leeuwenhoek discovered that later became known as bacteria","url":"https://time.com/4542058/antoni-van-leeuwenhoek-google-doodle/","keywords":["Newsfeed","Biology","Google Doodle"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt5b744a39d24d8605/6988ab2e97cdffb8366ae489/antoni-van-leeuwenhoeks-384th-birthday-5116176595156992-hp2x.gif?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Dominique Rowe","jobTitle":null,"url":"https://time.com/author/dominique-rowe/"}],"articleSection":"","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt5b744a39d24d8605/6988ab2e97cdffb8366ae489/antoni-van-leeuwenhoeks-384th-birthday-5116176595156992-hp2x.gif?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"antoni-van-leeuwenhoeks-384th-birthday-5116176595156992-hp2x","caption":"","creditText":"Google","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/tag/time-section-newsfeed/","name":"Newsfeed"}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/4542058/antoni-van-leeuwenhoek-google-doodle/","name":"New Google Doodle Celebrates Antoni van Leeuwenhoek, Inventor of Microbiology"}}]}] ```
